BALING- PRESS.

SPECIFICATION forming part of Letters Patent N o. 531,240, dated December 18,1894.

Application nea Mara ze, 1894..

To ctZZ whom it may concern:

Be it known that I, CHARLES E. WHITMAN, of the city of St. Louis, in the State of Missouri, have invented a .certain new and useful Improvement in Baling-Presses,'0f whichthe following is a full, clear, and yexact description, reference being had to the accompanying drawings, forming lpart of -this specification. l My invention relates to certain improvements in presses for baling hay, cotton, excelsior, and thelike; and my improved'machine is particularly adapted for baling hay or straw, either in its natural, long condition, or for baling chopped hay or straw, or other substances of vshort length, which are liable to be more dense at the bottom of the baling chamber than at the upper portion before the advance movement of the plunger.-

My invention consists in features of novelty hereinafter fully described and pointed out in the claims.

FigureI is a top or plan View of the baling or plunger end of my improvedpress. Fig. II shows this end of the press part in side view, and part in vertical, longitudinal section. Fig. III is a top or plan-view of the power end of thepress. Fig. IV isa detail, side elevation of the power end of the press. Fig. V is an enlarged, detail, longitudinal section of the baling endof the press, the plun` ger being shown in side view, and in'its advanced position. Fig. VI is a side view of the press folded for transportation. Fig. VII is an enlarged, detail, longitudinal section of the power end of the press, showing the plunger in its rear position. Figs. VIII and IX are detail views, showing a slight modification of the plunger; Fig. VIII being a side View, and Fig. IX a vertical section. Fig. X isan enlarged, vertical section of the power end of the press. Assuming that the sweep is in line with the length ofthe press, this section would be taken on line X-X', Fig. III. Fig. XI-is a top view of the power arms of the press. Fig'. XII is a detail, bottom view of the sweep casting.

Referringv to the`drawings, 1 represents the baling chamber of the press; 2, the hopper and 3 the plunger.

more material at the bottomof the'bales than 6o at the top, and when the bales are discharged from the press they assume a curved shape, and with rough handling, and sometimes with careful handling, theties slip from the bale entirely. To avoid this difculty, and at the Ysame time to make a press which may be used for either baling such short stud, or at will be changed for baling hay or straw in their natural, long state, is'one object of my invention, and for this purpose the plunger 3 has 7o in front of it a false head 4:. This head isl preferably so connected to the plunger as to allow it to move upward slightly as it assumes a vertical position, so that its lower end may always ride on the bottom of the baling chamber.

f The head is connected to the plunger. by

means of a rod or pin 5 passing through the plunger and fitting at its ends in slots 6, in

(See Fig. V.) 8o The side wings of the head lap over the sides of the plunger, as shown in thedrawings, and thus serve as guides to the'head aswell as forming a snug fit between the head and the side walls of the baling chamber. The lower edges 8 5 of the side wings are preferably inclined, as shown at 8, so 'as not tointerfere with the lower edge 9 of the head resting on the bot- (See Fig. VII.) When the plunger is in its rear position, 9o the head 4 assumes an inclined position, as shown in Figs. II and VII, and this may be effected by a rod 10 connected to the head and passing through a socket 1l in the plunger. Oli/the rod lO, back of the plunger, is a nut l2, which limits the opening movement. of the head et. Surrounding the rodlOis a spring 13, the inner end of which bears against. the end of the socket 1l,and the outer end of which bears against the head 4,-as, shown in 10o Fig. VII, or against a nut 14. on the rod 10, as shown in Fig. IX. The tendency of the spring is to hold the head 4. in its inclined position.v The head is provided with notches or grooves 15, to receive the retainers 1G, ordinarily used in baling presses, so that the retainers do not interfere with the movement of the head and plunger in their forward movement.

In Fig. VII I have shown the rod 10 extending back a considerable distance, with the nut 19 on its end, the rod passing through a bracket 17 secured to the inside of the bot tom of the press chamber. Surrounding the Io rod 10, back of the bracket 17, is a spring 1S, the inner end of which bears against the bracket 17. As the plunger moves forward, and before it reaches the retainers 16, the nut 19 comes against the spring 18, and pulls the lower edge of the head 4 up against the plunger, thus bringing the head into a vertical position before it reaches the retainers 16. VVth this arrangement the slots 15 may be made quite narrow, and only slightly wider than 2o the thickness of the retainers. In some instances, however, it may be more convenient not to have the rod 10 extend far back of the plunger, as shown inFig. IX, and in this case, the slots l5 should be made quite wide, and

z 5 on the arc of a circle, so that should the head 4 not be forced entirely back against the plun ger at the time the retainers are reached, still the retainers will be received by the grooves. When the plunger is in its rear position, the

3o inclined head 4 contracts the lower part of the space in the baling chamber which receives the stuit from the hopper, so that this space is smaller at bottom than it is at top, and owing to the tendency of short stuff or 3 5 material to pack at bottom, owing to its own weight, the amount of material contained in the space is approximately the same at top as it is at bottom, because of the space being larger at the top than at the bottom. As the 4o plunger advances, the pressure on the head 4 causes it to assume a vertical position,as shown in Fig. V. This vertical position is insured by the extension of the rod 10 and spring 18 in the construction shown in Fig.

4 5 VII, while with the construction shown in Fig.

IX, the head would assume a vertical posi-- tion, owing to the resistance of the material being baled, except possibly when there happened to be a very light charge.

As the plunger reaches the limit of its forward movement, and the final pressure is exerted, the head thus presents a vertical surface to the stuff being baled. The spring 13 is of suliicient force to prevent the head 4 5 5 from assuming a vertical position until the pressure on the stuff is sufficient to keep it from moving downwardly or packing under its own weight. When the plunger recedes again,the head assumes its inclined position 6o automatically, and thus the operation proceeds without attention from the workman. By providing for the vertical movement of the head 4, its bottom 9 always rests upon the iioor or bottom of the baling chamber. By 65 adjusting the nut 12, the inclination of the head may be regulated so as to make the rela tive size at top and bottom of the chamber,

which receives the material to be baled, whatever may be desired, according to the nature of the stud being baled.

By drawing the head back against the face of the plunger, and holding it there, by tightening on the nuts 10, the press may be used as an ordinary press for baling long material, and thus with my invention a baling press, at a very small additional cost, maybe used for baling either short or long material, at will.

I desire not to be limited to the exact matr ner of connecting the head to the plunger, either at its upper or lower end, as other means than the slots and pin may be used at the upper end and means other than the spring actuated rod l0 with nuts on its end may be employed at the lower end of the head.

represents a lever pivoted at 21 to the frame of the press, and one end of which is connected by a link 22 to the plunger 3. The other end of this lever is upwardly curved, as shown at 23, and to it is connected one end of a chain 24, the other end of which is connected to a rod 25 extending to the power end of the press. The ends of the lever 2O are connected together by a brace rod 26. The chain passes beneath a grooved pulley 27, and is held from lateral movement away from the pulley 27, by means of a roller 28. The pulley 27 and roller 28 are supported in a casting 29, hinged at 30 to the ends of two timbers 3l connected at 32 to castings 33 which su pport the press on the ground wheels 34. The outer ends of the timbers 3l are supported by legs 35 connecting them to the press chamber. The legs 35 are connected to the beams 3l, as shown at 36.

When it is desired to move the machine from place to place, or to store it, the beams 3l with the casting 29, are moved into the position shown in Fig. VI; the legs 35 having been disconnected from the beams 31 and turned on their pivots 35 into the position shown in Fig. VI when the parts are folded.

37 represents timbers adapted to be bolted to the casting 29, one on each side of the casting, as shown in Fig. I. These timbers cxtend back to the power end of the press, where there is secured to them a cross-piece 38, to which is bolted a casting 39, the outline of which, in top view, is shown in Fig. III, a side view of which is shown in Fig. IV, and a section of which is shown in Fig. X. This casting has an eye or opening to receive the hub 40 of the power arms 4l. The hub 40 is notched out, as shown at 42, Fig. XI, to receive a hub 43 ou a casting 44 secured to the sweep 45, the hub 43 having openings 46, (see Fig. XIL) to receive the hub 40 of the power arms 41; the hub of the power arms thus interlocking with the hub of the casting 44. The casting 44 is secured to the power arms by means of bolts 47, as shown in Fig. X. The power arms are formed on a sleeve 48, through which passes a piu or bolt 49 that extends also through the casting 44. The casting 44 has an arm 50, connected to the sweep by means of a brace rod 51.

' Fitting loosely on the sleeve 4s is the hub pin 58, having an upper roller 59, and a lower roller 60. -The pin 58 fits in a slot 6l in vthe cam 53, and the pin is kept normally at the inner end ofa slot by means of a spring 62 connecting the outer end of the arm 5G to the cam, as shown in Fig. III. As the sweep moves around, one of the arms 4l comes against the lower roller 60 on the pin 58, and moves the outer end of the cam in the direction of the arrow, Fig. III, thus imparting movement to the plunger of the press. Just asthe plunger reaches the limit of its ferr ward movement, the upper roller 59 on the pin 58 comes against a projection 64 on the casting 39, and forces the inner end of the` arm. 5G outwardly, disengaging the lower roller 60 from the arm 4l, when the parts will rebound to their normal position, and the next arm 4l coming against the roller 60 will cause the cam 53 to be moved again. The cam 53 has a ledge 65 on which the chain 55 rides as the cam is moved-around.

66 is a casting secured to the extreme ends of the timbers 37, and in which the lower end of the pin 49 is seated and upon which the hub of rthe cam 53, and the lower end of the sleeve 48 rest, as shown in Fig. X. By combining the cam 53 with the lever 20, together with their connecting parts that move them, a very powerful pressure is obtained.

70 represents the feeder. It is pivoted at 7l to the top of the baling chamber, and has an arm 72 carrying a counter-balance weight` 73. On the link 22 is pivoted an arm 74, the upper end of which is provided with a friction roller 75 bearing against the under side of the arm 72 of the feeder. On the pintle of the arm 74 is a counter-balance weight 75a, resting against a lug 76 on the link 22. As the plunger advances, the arm 74 forces the feeder 70 into the hopper of the press. When the roller 75 reaches a notch 77 in the arm 72, the feeder moves back to its normal position under the influence of a spring 78 and the counter-balance weight 73; the position of the roller 75 being, at this time, as represented by dotted lines in Fig. II. As the plunger recedes, the arm 74 moves back out of the notch 77 by turning on its pivotal connection with the link 22, and as soon as the plunger recedes the arm 74 is brought back to its normal position, and thereheld by the counterbalance weight 7 5a.

When the machine is to be moved or stored, the timbers 37 are disconnected from the cast# (ing 29, and run under the baling chamber,

over the front axle, as shown in Fig. VI, the

provided with bearings 66a to receive the front wheels, and when the parts are in this folded position, the cross piece 38 comes up against the ends of the lower timbers of `the baling chamber, as shown in Fig. VI, and is there held by a hook 79, or other fastening.
